AUTOlVfATlIC CELLAE-IURAXNER.

To all whom t may concern:

Be it known that l, ALEXIS R. Prism, a citizen of the United States ofAmerica, residing at Detroit, in the county of Wayne and State ofMichigan, have invented eercjtain new and useful improvements inAutomatic Cellar-lDrainers, of which the following is a specication,reference being had therein to the accompanying drawings.

The invention relates to an automatic drainer for cellars, sewers andother excavations arranged to discharge water noiselessly therefromwithout attention by the user, the parts being so disposed as to beaccessible for repair or replacement and being otherwise arranged tocombine simplicity with accura-cy of operation.

'llhe invention consists in the matters hereinafter set forth and moreparticularly pointed out in the appended claim.

ln the drawings, Figure 1 is a view in vertical section of an apparatusthat embodies features of the invention; and lFigs. 2 and 3 are views insection showing1 a modification of an ejector.

As herein shown an ejector casing 1 has a pressure inlet arm 2 openinginto a conical throat 3 with a discharge outlet nipple Il to which asuitable drain pipe 5 may be connected. A suction nozzle 6 is removablysecured in the casing with its jet mouth concentrically within thethroat 3. A suction pipe 7 is connected to this nozzle. rlhe lower endor mouth ofthe suction pipe is suitably secured in an opening of a dome8 on a cage 9 that may form a foot rest for the drainer and at any ratehas an apertured side wall as a strainer. An outwardly closing checkvalve may be placed in this cage and may be of any suitable design. Asshown herein an annular valve seat 10 is sealed by a vertically movableclosure 171 held in a depending stem 12 that reciprocatesin a guidebushing 13 of the cage. `Stop pins 1A may limit the upward movement ofthe closure.

` A Hoat operated-valve controls the How VV'through the inlet arm 2.This may be of any type, but preferably, consists of a casing 15 havin aair of alined valve seats 16 with a dou le anged closure 17 thereon,

this closure being arranged to have a balanced action. A stem 16depending from the closure, passes through a suitable packing gland 19and a guide bushing 20 in a depending arm 21 of the casing. A float 28has a central guide sleeve 22 loosely reciprocable on the stem,adjustable stop collars 23 limitings its movement.

lin li1 igs. 2 and 3 a modification of the ejector is shown in which theexhaust opening 241 is directly in line with a jet nozzle 25 that issupplied through a pressure inlet 26, and is disposed in the interior ofthe casing in substantial alinement with the suction inlet 2'? and thepassage or interior of the casing that connects this suction passagewith the outlet 2li. ln both constructions the jet nozzle, eithersuction or pressure, is removable and interchangeable with other jetnozzles to vary the proportions and consequent capacity of the ejector,or to meet different conditions or requirements of service. lWhen thewater level in the place in which the drainer is inserted, has reachedthe level sufficient to cause the iioat to raise the stem, the ejectorat once proceeds to draw water through the suction pipe owing to theaspirator action of the throat and suction nozzle and continues suchaction until the float has fallen sudiciently to close the valve. Thelimited movement of the float independently of the valve allows thecollection of a certain amount of water around the drainer before actionresults. While the foot valve or check in the suction pipe is anadvantageous feature it need not be used unless desired.

Ubviously, changes in the details of construction may be made without4departing from the spirit of my invention and l do not wish to limitmyself to any particular form or arrangement of parts.

What l claim is j n an automatic drainer, the combination with anejector having a drain pipe, and a suction pipe vertically aliningtherewith, of a cage supporting said suction pipe, a pressure inlet armcarried by said ejector intermediate the ends thereof, a valve carriedby said arm for admitting fluid under pressure 2' Liieiez to seidejector, e depending 2guide erm carfied by said Valve, a Valve stemextending through the arm of seid Valve into saidyalve to control theSupply of iluid to said pressure inlet arm, adjustable Stop collars onsaid Valve stem, and e float movable upon said Valve stem and limited inits movement thereon by said stop collars and adapted to i actuate seidstem at e time determined by the Volume of liquid to be drained. lo lntestimony whereof ll eiiix my signature in piesence of two Witnesses.
